Stay Away from Tracker

I need a zero star rating for this torture 😫 I recently bought a Jeep and called tracker to come install the units on my car, so I also decided to add this to a Polo that I also had for 4 years. Immediately after the installer left I drove Jeep and It had some dash errors, I then called Immediately for assistance and didn't win, weeks later I called and a technician came checked and said there's no errors, I let it slide because I was tired of this back and forth, then I also started driving the polo it also has similar errors (start stop off and some EPC light) for polo I managed to take a pic. Mind you the polo never displayed those errors before and it always had other tracking unit. Now they are telling me they are charging me R595 for callout fee. And when I cancel they tell me they want R5000+ that time I never enjoyed their service even for a day 😒
